FEBRUARY SKYNOTES 2019

 

February 2019

 

As the month starts, the Sun lies within the constellation of Capricornus, the Sea Goat until it crosses the border with Aquarius on the 16th at around 17h, where it remains until the month’s end.

 

The Moon

 

The Moon’s perigee (nearest to the Earth) occurs at 09h on the 19th, and apogee (furthest from the Earth) is on the 5th at 09h.

 

New Moon is on the 4th at 21h04 in the constellation of Capricornus, 3° south of the Sun..

 

 

 

First Quarter takes place on the 12th at 22h27 on the Taurus/Aries  border.

 

 

 

Full Moon is on the 19th at 15h54 in the constellation of Leo, just to the east of Regulus (alpha Leonis), Leo’s brightest star.

 

 

 

Last Quarter Moon is on Feb 26th at 11h28 in the northern part of Scorpius, near the Ophiuchus border.

 

 

 

Look out for ‘Earthshine’ illuminating the dark hemisphere of the waxing crescent Moon from the 5th to the 11th . Look also for earthshine on the waning crescent Moon from the 1st to the 5th and the 377th and 28th.

 

Earthshine is a beautiful naked eye phenomenon, but if you turn your binoculars towards the Moon, it is a truly magical sight.

 

The Planets

 

 

 

As February progresses, Mercury (in Pisces), becomes more readily visible in the evening sky and reaches its greatest eastern elongation (18°) on the 26th. Look for the planet in the western sky during the second half of the month between 18h and 19h, using binoculars to locate the planet in the fading evening twilight in that direction. As the month ends, you should be able to spot Mercury with the unaided eye, when, for example, just after 18h the planet is 11° above the WSW horizon. There is no other bright star-like object in that direction, so the planet cannot be mistaken for anything else.                

 

 

 

It becomes obvious during February that Venus is moving in towards the Sun. At the start of the month the planet rises three hours before the Sun, but only one hour at the end. Through a small telescope, the planet exhibits a gibbous phase. Lying in the constellation of Sagittarius, Venus passes 1° north of Saturn on the 18th.

 

 

 

Mars at visual magnitude +1 is visible in the evening sky as soon as it gets dark, until it sets at about 23h30 throughout the month. The planet is moving rapidly eastwards, crossing the Pisces/Aries border on the 12th. On the 13th at 22h, Mars is in conjunction with Uranus and the two planets are separated by an angular distance of 1° (two moon widths). Find Mars at an altitude of 12° in the west. Uranus lies to the lower left of Mars and has a magnitude of +5.8, so in order to see Uranus and Mars together, use binoculars, when at low power, they should be in the same field. The broad waxing crescent Moon is also in conjunction with Mars at 20h on the 10th. The Moon is 7° south of Mars at the time.

 

 

 

Jupiter rises at around 05h as February begins, but shortly after 03h at the month’s end. The planet is in conjunction with the Moon on the 27th, and the broad waning crescent just after Last Quarter will be seen approaching Jupiter, in the constellation of Ophiuchus, during the early hours of the morning. At 05h the two are just over 4° apart.

 

The season for observing the planet with its satellites is under way, so sharply focussed firmly fixed binoculars will reveal the disc of the planet and the ever-changing positions of the Galilean satellites.

 

 

 

As February progresses, Saturn becomes more readily visible in the early morning sky, and rises at around 05h at the month’s end. It is still at a low altitude in the constellation of Sagittarius and much dimmer (visual magnitude +1.3) than Venus (-4.0), further over to the left of Saturn by the end of the month. The two planets however, are in conjunction during the morning of the 18th, and should be looked for low in the SE sky at around 06h, when they are 5° above the horizon as twilight begins. At this time, the pair are separated by just over 1.5° (three moon widths). During 2019 the northern surface of the rings are still well-presented towards the Earth

 

 

 

 

 

Uranus is visible in the evening sky, but sets by 23h mid-month. Its conjunction with Mars has already been noted. The path of the planet throughout the month on the Pisces/Aries border, can be found on the Remote Planets page via the MENU/MORE tab.

 

 

 

Neptune, isstill in the constellation of Aquarius, and is visible for a short while as a faint object in binoculars or a telescope in the early evening, at magnitude +7.9. On the 19th at 18h, and 6° above the western horizon, Mercury is in conjunction with Neptune, when the two are separated by just over 1°, Neptune lying to the south of Mercury. As there is still some degree of twilight in the sky, this is a difficult observation because of the faintness of Neptune. Look at the Remote planets page for the path of Neptune throughout 2019. It is interesting to note that two of the brighter inner planets, Mercury and Mars are in the same line of sight as the two far dimmer and remote gas giants, Uranus and Neptune.

 

 

 

 

There are no major meteor showers during the month, and so we expect to see the normal background rate of four noticeable events during each hour of the night.
